Have had several long conversations with Susan.

She already checked with her VOM at the ATS-- showed incorrect wiring, though wire colors at ATS are correct.

CG pedestal showed correct wiring (voltage good, correct socket wiring).

That leaves two suspects:
Wiring of "side of the coach" outlet where shore power cord connects to coach wiring (the most recent pictures she posted).

AND

The shore power cord itself-- which she says HAS been run over.  We talked through checking the readings between the male (CG) end and the female (coach) end of the cord with her VOM. Check for correct readings (zero Ohms= continuity) between prongs on male end and what should be the corresponding socket on the female end AND making sure there from each prong on the male end there was an open circuit (infinity reading) to all other sockets on the female end.

Even though using volt meter to check pedestal, trying another pedestal (if possible) could not hurt.

Or if park will change breaker and "especially" receptacle......

That's where having a EMS is great. The 'Park'  where we fried our ATS & wiring changed the breakers AFTER our meltdown, though NOT admitting the meltdown was on their nickel!  >:D

Add-on: here's a better info sheet for the EMS.
